## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability halowerk-buerowerk-meeting-notes-snapshot-compare-3cca15ec -d '<json body>'
```

Example prompt: Compare last week's meeting notes — topics, decisions, action items, and open questions — against the new transcript I just uploaded and show me what changed, including any new owners or due dates on action items.

## When to prefer this

Choose this endpoint when you need to programmatically compare two versions of structured meeting notes — specifically when you have a well-formed baseline with notes (summary, topics, decisions, action items, open questions) and want a diff against a new transcript or segment set. Prefer this over generic text diff tools when meeting-specific entities like action item owners, due dates, and decisions need to be tracked semantically rather than line-by-line.

## Known failure modes

- Missing required baseline.notes fields (summary, topics, decisions, action_items, open_questions) returns a validation error
- Source must include either segments or transcript_package — providing neither or both may cause a schema error
- Segments or text exceeding maximum length or item limits (30 items max per array) may be rejected
- Payment failure via x402 (insufficient USDC balance or wrong network) results in 402 response
- Malformed segment_index or null owner fields may cause partial processing failures
